What's inside —
What Segmentation Should Help You Decide
Start with the campaign decision before creating a new audience rule. This chapter shows how to connect segments to message relevance, timing, follow-up, and a practical first set of groups.
Collecting Signals That Are Useful
Choose preference data and behavioral signals that have a visible use in future campaigns. Includes the Signal Inventory Map for recording data sources, time windows, and direct campaign applications.
Building Segments You Can Use Consistently
Write clear inclusion and exclusion rules, distinguish dynamic audiences from snapshots, and name each segment so the team can maintain it. Includes a fill-in Segment Design Canvas.
Turning Segments Into Better Campaigns
Match the message, frequency, and follow-up to the strength of the signal. A worked webinar example and campaign worksheet show how to make one relevant change and measure it clearly.
Measuring and Refining Your Segments

What You'll Learn
A five-step process for collecting useful subscriber signals, creating audience rules, applying them to campaigns, and reviewing the results.
Define the campaign decision
Choose a communication decision that a segment should change, such as who receives an invitation, which content version they receive, or what follow-up they need. Write the purpose in plain language before creating a rule.
Identify useful subscriber signals
List the preferences, profile details, recent actions, registrations, purchases, survey responses, and engagement patterns that relate to the decision. Collect new information only when it will change a future communication.
Create a clear audience rule
Define the inclusion conditions, exclusions, time window, and whether membership updates dynamically or records a fixed event. Name the segment so another teammate can understand the audience and its purpose.
Apply the segment to a campaign
Change one relevant part of the campaign, such as the content, call to action, timing, frequency, or follow-up. Set a frequency limit and exclusions for subscribers who may qualify for multiple campaigns.
Review and refine the segment
Measure the outcome that the segment was designed to improve, then review its size, rule logic, data quality, exclusions, and subscriber response. Keep, adjust, combine, pause, or retire the segment based on that review.
